BOTTLE cAP Filed March 28, 1940 9 AMA/v POzS/NJO/V //v VEN r01? QJMWW Patented Apr. 1, 1941 UNITED STATES PATENT OFFICE BOTTLE CAP Allan Robinson, Roxbury, Mass. Application March 28, 1940, jSerialNoJ32 6A (or. 35-59) I l' 6 Claims.

The present invention relates to a bottle cap and in particular to a cap for a bottle containing nail polish or the like and may be applied to any type of bottle, either a screw can type, ground fit stopper or any other type of cover or stopper whatever may be most desirable under the circumstances.

In most types of bottles which are used for nail polish, it is impossible to learn from the color of the polish in the bottle just how it will look on the users nails. In some cases the color is displayed on the side of the bottle and while this gives somewhat of an idea as to how the color will look on the finger nail, it still lacks in giving a contrast to the actual hand upon which the color is to be used. The present invention not only eliminates this difiiculty as will be seen from the specifications below, but also provides a stopper or cap which is easily removed I from the bottle by virtue of its shape and further provides a better grip for the hands in using the bottle.

The present invention may take various forms and some of these are described in the specification below in connection with the drawing in which Figure 1 shows a plan View of the cover in one position.

Figure 2 shows a side elevation of the cover shown in Figure 1.

Figure 3 shows a sectional view taken on the line, 3-'3 of Figure 1 with a top element in position.

Figure 4 shows a modification of the sectional view shown in Figure 3.

Figure 5 shows a plan view of a further modification in the same position as shown in Figure 1.

Figure 6 shows a side elevation of the view shown in Figure 5 with the top element in a closed position.

Figure '7 shows a sectional view of the cover shown in Figure 6 taken on the line 'l-'l of Figure 5.

Figure 8 shows a modification of the device shown in Figure '7 in the same view.

Figure 9 shows a further modification of the device shown in Figure l, and,

Figure 10 shows a section on the line l0l9 of Figure 9.

As will be seen from Figure 1 the bottle cap comprises a base member I which is shaped like a sharply trimmed ladys nail having a substantially elliptical portion corresponding to the portion of the nail in the vicinity of the cuticle and a pointed portion corresponding to the nail end. The base I is provided with a recess 6 which may be threaded as indicated at 'l to retain the bottle or any other method of attaching the bottle to the cap may be usedg such as an external or an internal ground tapered fit or a force fit or a plain catch fit.

At the top of the base I there is provided a cap or disc 2 which is pivoted to the base at the tip portion 4 by means of the pivot 8 which may be a metal pivot if desired or may be a molded pivot such as is shown in some of the other figures.

The top disc2 is shaped like the base I with the tip 1 corresponding to the tip 3 of the base and the side edges corresponding to the side edges of the base. Theno-n-pivoted end of the cap member is formed in a concave arch 5 representing the half moon or the cuticle, while on the base I at the larger end there is a projection l l which has its surface fiush' with the top of the cap 2. The disc 2 maybe" made'convex asin the shape oi a nail and given the coating of polish in the bottle. The'raised portion ll of the base level with the disc 2 and representing the cuticle can be given alight ivory color or light flesh color in the shape that usually appears on the half moon of the nail. The concaved end 5 of the disc 2 will be made such that it will clear when rotatedthe portion ll atthe end of the base.

The top disc may be (turned around from its normal position to 1181)? .andthe individual may compare the color of the disc with that of her own nails by putting her nail beneath it or against it, and if she wishes. to see how the color will look on the finger the disc may be placed over the entire nail in the position that the nail polish usually occupies.

In the modification shown in Figure 4, the recess l5 for the cap is in the center of the base rather than at the end of the base as in the other figures. This cap may be threaded as indicated at M and the base It! may similarly, as in Figures 1 to 3 be provided with a raised end portion l2 and a cap or disc [3 which is slightly convex (transversely) in shape.

In the modification illustrated in Figures 5, 6 and 7, the base of the bottle cap is made to have a heavier portion 22, wherein the recess 23 is made to receive the top of the bottle with a lighter thinner base l9 forming the top of the base in which the top cap or disc 2| is pivoted by the pivot 20. This construction may save some of the material that is otherwise necessary in the modification of Figures 1 to 3 and may also furnish a better grip for opening or closing the bottle.

In the modification illustrated in Figure 8, the cap is made of a heavy central portion I! with a recess l8 and an external flange at both sides as shown by H5, in one side of which the top disc is pivoted as in the modification of Figures to '7.

In the modification illustrated in Figures 9 and 10, the base 34 is shaped somewhat similarly as that shown in Figure 1. In. thi case however the top disc which is pivoted by the pivot 31 to the base 34 is made similar in the back portion so that the top surface of the base 34 forms a border around the back portion of the disc 30. This back portion of the base 34, or in fact the whole of the base 34 may be given the ordinary flesh color and the convex cap 30 given the color of the polish in the bottle. This modification will therefore represent the nail polish as applied to a conventional finger. If the individual Wishes to see how this polish will suit :her nails, she will rotate the cap 30 around one half turn and then put her finger beneath the disc 30, getting thereby a comparison of the color with her finger.

Shapes and for-ms of nails other than those indicated here, may if desired be used; but in general it is desirable to have the nail shaped in the general form of a properly trimmed finger nail. I

The cap may be constructed of any typeof material such as molded plasticspfor instance Bakelite or any other type of material which will readily take the colors desired.

Having now described my invention, I claim: 1. A cap for a colored finger nail polish bottle shaped substantially in the form of a finger nail, a disc element colored like the polish in the bottle having a similar shape but slightly smaller at the rounded end whereby the top surface of said cap. portion shows around the sides and back of said disc element, means pivoting said disc element to said cap at a point corresponding to the nail end of said finger nail to permit said disc element to be rotated sufficientlvaway :from the cap .for a person to put his finger thereunder to obtain an estimation of how his finger nail similarly colcred would appear, said disc-element being slightly convex in its transverse section.

2. A-cap for bottles for colored nail polish hav-.

ing an element colored like the polish in the bottle and simulating .a fingernail, said element being mounted on the cap of said bottle at the end corresponding to the point of the finger nail and extending sufficiently away from the cap for a person to put his finger thereunder to obtain an estimation of how his finger nail similarly colored would appear.

3. A cap for bottles for colored nail polish having an element colored like the polish in the bottle and simulating a finger nail, means mounting said element to pivot in said cap in the top near the side thereof, said pivot being at the end of the element corresponding to the point of the finger nail and being rotatable to bring the other end of the element sufficiently away from the cap for a person to put his finger thereunder to obtain an estimation of how his finger nail, similarly colored would appear.

4. A cap for bottles for colored nail polish having the top thereof in the shape of a finger nail, a thin member colored on top like the polish in the bottle and simulating a finger nail, means mountingsaid member to pivot in said cap in the top near the side thereof, said pivot being at the end of the member corresponding to the point of the finger nail and being rotatable to bring the other end of the member sufficiently away from the cap for a person to put his finger thereunder to obtain an estimation of how his finger nail, similarly colored would appear.

5. A cap for bottles for colored nail polish having the top thereof in the shape of a finger nail, a thin member colored on top like the polish in the bottle, simulating a finger nail and being slightly smaller than the top of said bottle, means mounting said member to pivot in said cap in the top nearthe side thereof, said pivot being at the end of the member corresponding to the point of the finger nail and being rotatable to bring the other end of the member sufficiently away from the cap for a person to put his finger thereunder to obtain an estimation of how his finger nail, similarly colored would appear.

6. A cap for bottles for colored nail polish having an element colored like the polish in the bottle and simulating a finger nail, means mounting said element on the top of said cap of the bottle for extending said element sufiiciently away from the cap for a person to put his finger thereunder to obtain an estimation of how his finger nail similarly colored would appear.
